Usually colorization is put in action via alias : alias ls=’ls –color=auto’
You can turn off the colors each time you run ls: ls –color=never l or change the alias itself to disable fancy colors permanently or even simple \ls . But to change the colors you’d need to cause dircolors utility to read your own color database when the login session starts. So let’s do just that
1) Export existing db:
[bash]dircolors -p > dircolors.db[/bash]
2) edit :
[bash]vi dircolors.db[/bash]
e.g. change directories color from blue to red:[bash]di=01;34 -> di=01;31[/bash]
3) save changes
4) make bash to reload color scheme:
[bash]eval `dircolors dircolors.db`[/bash]
5) put [bash]eval `dircolors $HOME/dircolors.db`[/bash] into .profile file at the end of it.
That is it.

There are 50 ways to do PTR resolving in bulk,and this is just one of them. It doesn’t pretend to be the fastest/coolest/best, the only thing
I can claim – it works. So use it for pleasure and work.

# this script accepts range of IP addresses to do PTr resolving for
# the range has to be in this format: startIp-endIp.startIp-endIp.startIp-endIp.startIp-endIp.
# Only answers are printed, i.e. if there is no answer nothing is printed

Trying out Amazon AWS Glacier with fastglacier.com as the upload GUI app I looked at few SHA256 sum calculating tools, and found this one by Jesse Kornblum to be the best for Windows.
It has some quite useful options like recursive folders calculation, file size limitation, reading file names from file and hash comparing. Be aware it is command-line only.

May be not new , but new to me – spam mails that instead of direct links to their websites list links cached in google. So , you get in the email not http://degayfisk.com/ but http://google.nr/search?q=cache:c2tHRUQ2mx4J:google.co.nz
It is ,by the way, recognized by eSafe 8.5 as a Clean mail, what a shame.
